On February 17th, late night host Jimmy Fallon will take over 'The Tonight Show' and naturally famous guest stars will be joining him for the inaugural affair. Fallon recently revealed that Will Smith will appear on the show in addition to a special performance by U2. The band is expected to release a new album in April, therefore raising speculation that they may be unveiling some new material on the show.

Fallon is scheduled as a guest on Jay Leno's Tonight Show on February 3rd, presumably to openly discuss and joke about the handover arranged by NBC. Then Leno's last show will be February 6th before Fallon takes his place and Saturday Night Live's Seth Meyers will take Fallon’s former late night time slot.
